sTEmLlzED ERECTED POLE.

v No. 837,826.

To aZZ whom it mwgfconcern;

Be it known that we, HENRY PAGE FoL- soM and HOWARD JoNEs', .citizens of the United States, and residentsof Circleville, in the county of` Pickaway and State of Ohio,

have invented new and useful Improvements in the Art of Sterilizing Erected Poles, of which the following is a full, clear, and exact Our invention relates to the sterilizing of poles which from their erection in the ground ave-become infected by bacteria and fungi and attacked by insects,l resulting in the decaand destruction of a portion of the fpoles. Veretofore antiseptics have been orced .into the structure of the wood before it is used by. various processes; but these substances in contact withthe'. moisture of the earth when the poles are set soon volatilize or dissolve. Antiseptics have also been smeared upon the surface of oles after erection; but these are in a simi ar manner soon dissipated and lose their eflicacy:

Our invention aims to obviate these difficulties and to secure and maintain a-sterile condition of poles for long periods.

Reference 1s to be had to the accompanying drawings, formin -a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 shows a pole with one form of our invention applied thereto, the excavation about the decayed portion being indicated. Fig. 2 is a vertical section therethrough on the line 2 2 of Fig. 3, with the earth restored.

Fig; 3 is a horizontal section on the line 3 3 of Fig. 2, and Fi 4 is a central vertical sectional detail o another form of our invention.

A pole P is shown set in the ground, the upper surfaceof which is indicated at G. It

being desired to sterilize this pole, the vsurrounding earth is excavated at G until the infected portion is exposed. The decayed Wood is t enpreferably scraped away until sound material is reached. The cavitiesthus exposed in the pole may be illed with a oWdered or lastic antiseptic which is a acteriacide, ngicide, and insecticide. This having been accomplished, one or more sheets of preferably flexible material 10 are placed about the pole and lapped at 11, the ap'being cemented with asphal'tum or other moisture-resistive adhesive and riveted or otherwise secured at 12 to form a sleeve en Specification of Letters Patent.

circling the pole, leaving an xintermediate space. While ,the material of this sleeve may be of non-corrodible metal or sectional\ .,v

tile, we prefer to form it offs'uccessive layersl' of asbestos paper or thin board cemented to one another by asphaltum or the like. The bottom of the space between the pole and sleeve is closed by a packing '13, saturated' with asphaltum or` a like adhesive to seal this extremity of the sleeve against moisture and furnishing a receptacle.. `Into this receptaele is laced an antiseptic.. 14, which may be simi ar to that applic to the cavities in the pole, this extending from the packing to the top of the sleeve. Here the sterilizing material may be applied in plastic form and inclined upwardly at 15 from the edge of the sleeve to the ole. A collar'16 is then applied to the po e with its joint 17 suitably secured and is attached to the pole at 18. This collar furnishes a protecting cover inclined downwardly over the edgeA 'of the sleeve. The excavated earth is returned and tamped about the pole, this not being permitted to rise above the top of the sleeve.

It will be seen that the antiseptic con- -tained within the receptacle will not only eHectively sterilize the pole to which it is applied, but as it is protected against the action of water will be retained and will exert its influence for a lon time, during which the sterilizing materia will be taken up by the natural moisture of the pole, and thus distributedu the sappy portion of the pole a considerab e distance above the sleeve' by capillary attraction and other natural means, as Well as throughout a much greater portion of the structure than its exterior. v

In Fig. 4 we have shown an auxiliary protecting-sleeve' 19 surrounding themain sleeve 10 near the surface of the ground, this serving to resist crushing when the earth is restored. We have also illustrated a covering 20 of Portland cement or the like, which crowns the top of the receptacle, taking the place of the plastic antiseptic and furnishing a more com lete seal.

While the term po e is used throughout the description and claims, it should be noted that the invention is not only applicable to such objects as telegraph and other poles fcr carrying overhead work, but also to fenceposts and the like.

The packing 13 should be partially impervious'to'water, butV it is not necessary for it to be wholly so. Its purpose is primarily to IOO IIO

prevent Water entering and leaving 4the Ainterior of the sleeve Withireedomsufficient-'to destroy or Wash awav the chemicals. vlll/'hen the packing is Fartia lyimpervious,the water Which 'enters s owly dissolves a portion of the chemicals and soaks into the pores of .the pole, impregnating them, which is beneficial. As the Water dries out slowlyfthe chemicals in solution Will crystalize out, so that they lose 4little of ftheir quantit or quality.

The antiseptic pac `ng 14rnay havecom-v mon salt as -a base; but -We have found that an antiseptic having sulfate efcopper :as a

base and 4clean Isand yand-clay in suitable 'proportions gives the -best results. This mix- 'fture has Athe Iadvaninenge of :not affecting the asbestos sleeve.

l'Having 'thus described our invention, lWe

claim asnew and :desire 'to-secure -by ILetters -Patentv 1. The 'combination With-a'pele, ofasleeve encircling the pole and spaced 4apart therefrom, a acking situated between the pole and ,the's eeve, fne-arthe lower end thereof to form a receptacle, :receptacle-and -acovering connected with the polie and extending over thefoop ofthe receptac e.

2. The combination with a pole, of a sleeve surrounding andbeing separated therefrom,

an antiseptic iilling for the i a packingv situated between the pole and A sleeve near the lower extremity of the latter to :form a receptacle, al1/.antiseptic filling for "t he vvrece tacle, and a collar secured-fte fthe xpole :an extending over the upper edge .of

the sleeve.
